[PATCH] mod_devicetable: helper macro for declaring oftree module device table

[Enrico Weigelt, metux IT consult]

Little helper macro that declares an oftree module device table,
if CONFIG_OF is enabled. Otherwise it's just noop.

This is also helpful if some drivers can be built w/ or w/o
oftree support.

As I said before, please drop all "non-name" information from your s-o-b
line.

Do you have a real user of this?  We need that for any type of apis that
people are supposed to use, we do not just add them without users if at
all possible.

And did you run it through checkpatch.pl before sending this?  :(

thanks,
